I ran across this article, Eight Simple Tips for Editing Your Own Work, and thought I’d post the tips here.  For further discussion, see the linked article.

1.  Don’t edit while you are writing.

2. Put your work aside for a few days.

3. Read it through in a different format (I think they mean font, here).

4. Edit for structure and content first.

5. Cut out 10% of your words.

6. Use spell check, but use your eyes too.

7. Read your piece backwards, or slowly.

8. Let it go.

To these I’ve added one that I find particularly useful, especially for dialogue.

9. Read your work aloud.

There, nine tips for editing that will make your work better. I hope this helps.
